Li Gou 李覯 (1009-1059), courtesy name Li Taibo 李泰伯, style Xujiang xiansheng 盱江先生, was a Confucian scholar of the early Northern Song period 北宋 (960-1126). He came from Nancheng 南城 in the military prefecture of Jianchang 建昌軍 (modern Jiangxi) and was a private teacher who owned his own institution, the Xujiang Academy 盱江書院. In later years he was recommended by the politician Fan Zhongyan 范仲淹 and appointed instructor (zhujiao 助教) in the National University (taixue 太學) and then lecturer (zhijiang 直講).
As a native of the region of modern Jiangxi Li Gou belonged to a group of thinkers that fundamentally changed the political and philosophical landscape of China, like Ouyang Xiu 歐陽修 or Wang Anshi 王安石. His political thought influenced the practical measures that Fan Zhongyan took in his reform politics of the Qingli reign era 慶曆 (1041-1048, Qingli xinzheng 慶曆新政), and also the reform politics of Wang Anshi in later decades. Li tried to combine philosophical ideas with a practical application of these in the field of politics. Li Gou analysed the ritual classics Liji 禮記 (in his book Lilun 禮論) and Zhouli 周禮 (in his text Zhouli zhi taiping lun 周禮致太平論 "The Rites of the Zhou will lead to the Great Peace") to find practical advice in them for the government of a state. In his short book Changyu 常語 Li Gou criticized the ancient philosopher Mengzi 孟子 who had introduced the theorem that profit (li 利) was less important than righteousness (yi 義), which had led to the overall neglection of mercantile business by Chinese governments. Yet he defended Confucian thought against the influence of Buddhism and Daoism and so stands in one line with the Tang period 唐 (618-907) thinker Han Yu 韓愈. The rejection of the two religions finally led to the ban on religious thought in politics during the Qingli reign.
Li Gou has also written a book called Qingli minyan 慶歷民言 "Words about the people under the Qingli administration". His collected writings are called Xujiang wenji 盱江文集 or Xujiang ji 旴江集 (also called Zhijiang Li xiansheng wenji 直講李先生文集, and in a modern edition Li Gou ji 李覯集).
